M14 Shooter
The Light of Truth
The current background check system is designed specifically to take as little time as possible - so, no.No, having to go through the background check is going to slow you up isn't it...You're talking about the fabled "cooling off period" not background checks.No, but it might "prevent" you from having the tools that you wanted to carry out the murder/robbery/rape easily to hand.
If you didn't plan to carry out the murder/robbery/rape but a rush of blood/testosterone/alcohol to the head pushed you into it a background check might just give you enough time to re-think/jerk off/sober up and change your mind.
But I guess the goalposts aren't going to move themselves.
